Abstract

Waterborne parasites are primary parasites that are ubiquitous and affect humans, pets, and wildlife throughout the world. According to the World Health Organization, more than 80 human diseases transmitted by water in developing countries, 60% of the population do not have access to clean drinking water .Waterborne diseases occur worldwide, and outbreaks caused by the contamination of community water systems have the potential to cause disease in large number of consumers. This study dealt with the database of studies of waterborne parasites in Iraq. Which includes the following classes of parasites: Nematodes as Ascaris lumbericoides, Trichuris sp., Strongyloides stericorailis and Enterobius vermicularis. Cestodes as Taenia sp. and Hymenolips nana. Trematodes as Fasciola sp. and Schistosoma haematobium. Protozoa as Entamoeba histolytica, Trichomonus vaginalis, Chilomastix sp., Iodamoeba butschlii, Naegleriae sp., Coccidia sp., Acanthamoeba sp., Cryptosporidium parvum, Cryptosporidium muris, Giardia lamblia, Blantidium sp., and Entamoeba coli.

Keywords: Water born; Entamoeba histolytica; Giardia lamblia; Ascaris lumbricoides; Iraq

1. Introduction

Water is the main ingredient on earth It is vital to all known life forms, and It is an essential nutrient for proper maintenance of homeostasis in the human body. It exists in liquid, solid, and gaseous state [1]. Water is used for more than drinking, it is used for swimming and irrigation, livestock watering in agriculture and boating in recreation, or for industrial activities such as paper and pulp production. It is important that drinking water is kept, safe, clean and reliable [2]. Water is referred to as a global solvent because it can dissolve more substances than any other liquid; the nature of the solvents allows water to contain both beneficial and harmful substances [3]. The community water systems infections may lead to outbreaks of diseases that are likely to cause the disease in large number of consumers [4,5]. Research interest in drinking water contamination by intestinal protozoa has increased significantly over the last three decades, and a number of human parasitic infections are transmitted through the water-borne pathway [6]. Waterborne parasites are primary parasites that are spread everywhere and affect humans, domestic animals and wildlife around the world. Minimum of 325 water related outbreaks of parasitic protozoan diseases have been reported around worldwide [7]. There are many factors that contribute to the spread of diseases, including heavy rains, water, and agricultural residues, which will transport the parasite to surface water through soil [8]. Therefore, contaminated household water tanks are one of the main causes of intestinal diseases transmitted in developing countries [9].Waterborne diseases worldwide are among the most common diseases that kill children under the age of five , and more people die each year from unsafe water than from all forms of violence, including war [10]. There are four main categories of water-related diseases: waterborne (orally), water-washed, and water-related insects. Many water-related diseases are the result of poor quality water that is used for washing, drinking, and other uses [11]. The aim of this study was to define an important reference for all researchers and authors who plan to study the field of water-borne parasites more comprehensively in the future

2. Waterborne parasites in Iraq

In Iraq there are many areas that do not have sewage systems with toilet discharge under the houses, and there are also many areas that empty sewage discharge into rivers [12]. Hadi and Faraj [2] in their study for distribution of intestinal parasites in drinking water in some regions in Baghdad province, Iraq (Hi-Al-Maalf, Hi-Al-Jehad, Al-Dura, Al-Shabab and Al-Baya'a), they found the total contamination rate in sewage water was 60% with these parasites: Ascaris lumbericoides, Entamoeba histolytica, Fasciola sp. and Strongyloides stercoralis, in tap water was 17.2% . Hussein [13]. who study the prevalence and associated risk factors for Giardia lamblia infection among children with acute diarrhea in Thi- Qar , who explained that acute diarrhea is a major public health problem in Iraq, drinking raw or municipal water, hot seasons, and living with four or more children staying at home were significantly associated with lamblia giardiasis infection (p

3. Conclusion

The current study reviewed waterborne parasites in Iraq and an important reference for all researchers and authors who plan to study this field more comprehensively in the future. Our study revealed many intestinal parasites that transmitted by sewage water can lead to cause diseases in both human and animals. Protozoa that causes disease as Cryptosporidium sp., E. histolytica and Giardia Lamblia were more prevalence in fresh and tap water in some provinces of Iraq.
